Ray Manzarek's marriage certificate and the handwritten lyrics to Jim Morrison's first poem have been added to the Rock + Roll Hall Of Fame as part of a new 40th anniversary tribute to The Doors.
The Doors memorabilia was added to the Cleveland, Ohio museum when the group was inducted to the Hall Of Fame in 1993, but new items have been added to coincide with a new Break On Through - The Lasting Legacy Of The Doors exhibition.
The show is the first to be endorsed by Morrison's family.
The new items also include Robby Krieger's custom Gibson guitar and a promotional record that came with purchases of toothpaste and shampoo.
But the highlight is sure to be the poem Not To Touch The Earth, which tragic frontman Morrison's wrote when he was a child.
